Content removed from the vault?

At some moment the City16 project was removed from my safe, is no longer available in the Epic Games store and also on the page: Learn, what happened?
I added the free project to my safe a year ago but only decided to use it now and I can’t find it anymore.

Hello,

The project you’re pointing to is called “Showdown VR Demo” and is accessible via the Learn tab.

Thank you .
